Error unrecognized key after upgrading to latest melpa Hydra

[dahanbn]

After upgrading to the latest hydra (20150423.653) from Melpa I am not able to initialise the following hydra:

(defhydra dh-hydra-markdown-mode (:hint nil)
  "

After starting my Emacs I got the following debug backtrace:

The hydra worked before. Do you have any idea?

Thanks for reporting, should work now.

[dahanbn]

Yeah. It works now. Thanks a lot for the quick fix and your amazing lisp coding. :-)

I'm getting a similar error with the 20150423.1401 update. Hydra is no longer recognizing "-" as a head. It gives me an error:

Debugger entered--Lisp error: (error "Unrecognized key: __: volume down     _")
  signal(error ("Unrecognized key: __: volume down     _"))
  error("Unrecognized key: _%s_" "_: volume down     ")

@jagrg, you mean the minus symbol? I've just checked that it works:

(defhydra hydra-toggle ()
  "
_-_ abbrev-mode
"
  ("-" abbrev-mode nil)
  ("q" nil "quit"))

[jagrg]

Try this

(defhydra hydra-buffer-menu (:color pink
                             :hint nil)
  "

@jagrg, thanks. Should work now.
